    • A device for producing compacts having main cylindrical elements and helically-shaped secondary elements from a powdery material, in particular a metal powder, has a female mould (1), at least one upper punch (2) mounted to rotate around its longitudinal axis and at least one bottom ram (3) mounted to rotate around its longitudinal axis. The upper punch (2) and the bottom ram (3) are motor-driven in the axial direction in relation to the female mould (2) and the upper punch (2) is rotated around its longitudinal axis besides being axially driven in order to describe a helical movement. The invention is characterised in that an electronic control (8) is provided, in that the bottom ram (3) is also motor-driven and in that the motors that rotate the upper punch and bottom ram (2, 3) are mechanically uncoupled from the motors that axially drive them and may be separately regulated by the control (8).
    • 本发明涉及一种装置,用于产生具有圆柱形主元件和从粉状材料螺旋二级成形元件,特别是金属粉末成形体,与模具(1)和具有至少一个绕着其纵向轴线可旋转地安装上模(2)和至少一个绕着其纵向轴线可旋转地安装 下冲头(3),其中,所述冲头(上冲头(2)和下冲头(3))在轴向相对于所述模具(1)由可移动的电机和所述至少一个上冲头(2)驱动,以在除了其轴向驱动在围绕旋转实现的螺旋运动其 轴被驱动。 本发明的特征在于,电子控制设置(8),所述至少一个下冲头(3)也被驱动旋转,并且所述冲头的马达旋转驱动器(2,3)中的每个(的驱动器用于柱塞的轴向移动 2,3)被机械地去耦,并且分别(通过控制器8)可以被调节。
